Downton Abbey

It's almost time for Michelle Dockery and the rest of the Downton Abbey cast to say goodbye after six seasons. But first, the actress, 33, who plays Lady Mary in the beloved British period drama, will get as many pictures as she can for posterity.

The Golden Globe and three-time Emmy nominee is documenting the final days of production in a series of photos that she is tagging #LastDaysOfDownton.

So far, she has been focusing mostly on the off-screen talent, including producers and crew who've worked behind the scenes to make the program, which premiered in 2010, such a success.

Though the show's massive international success could hardly have been anticipated, Downton Abbey star Hugh Bonneville is somehow "amazed" that the award-winning show went beyond its first season – as was everybody else involved.

"Those who follow the show might remember at the end of [season] 1, there was a slightly odd feeling because some of it was wrapped up in case the show never returned and some of it was led to pen in case it did – so, there was no guarantee the show was going to continue," Bonneville, 51, told ITV's Good Morning Britain.

After confirming on Thursday that Downton Abbey will conclude after its sixth season, executive producer Gareth Neame discussed the decision, admitting, "It's a very emotional day for all of the people involved in the show."

"The danger with this sort of thing is to let them go on forever," Neame told reporters during a conference call.

Neame stated repeatedly that ending the show was a joint decision between producers and cast. He also dismissed claims that creator Julian Fellowes solely forced the issue or that the show is shuttering under pressure from exiting cast members (particularly Golden Globe winner Maggie Smith), falling ratings or the show's networks (ITV in the U.K., PBS in the U.S.).
